1. Magpul AR-15 30 Round PMAG Gen M3
Key Specs:
- Caliber:
5.56x45mm / .223 Remington
- Capacity:
30 rds
- Material:
Polymer
Pros:
- Better durability and lifespan than USGI magazines.
- Excellent reliability.
- Reinforcement around feed lips and magazine catch for better durability in high stress areas.
- Viewing window shows you how many rounds are left in the magazine.
Cons:
- Doesn’t fit all lower receivers.
The Magpul AR-15 30 Round PMAG Gen M3 has been a staple for AR-15 shooters for decades. The PMAG is so popular that some manufacturers include PMAGs with their rifles.
This magazine is one of the original polymer magazines (it might even the THE original polymer mag).
Polymer retains its reliability better than metal after repeated drops that can cause metal magazines to deform over time. The polymer construction also solves the problem of warped feeder pawls that have plagued metal USGI magazines since they were invented.
So, this magazine is more durable and delivers a longer service life than almost any competing metal magazine. And, it’s actually lighter than some metal magazines, too.
There’s also reinforcement around the magazine catch and feed lips to make this magazine more rigid. Inside the magazine, there’s a four-way anti-tilt follower to help rounds feed more smoothly. These features help improve reliability with all types of ammunition
Additionally, this magazine is equipped with a viewing window that enables you to see how many rounds you have left in your magazine for better tactical reload timing and on-the-fly adjustments. You can also get the PMAG without the viewing window for a few dollars less.
If you want more rounds in your magazine, check out the 40 round PMAG Gen M3 Magazine. It’s the same as the 30 round PMAG, but with more capacity. It’s an excellent option for competition shooters who need a lot of rounds to get through stages without reloading.
The only issue with the PMAG is that the overtravel stop doesn’t fit some lower receivers. This magazine fits most standard lower receivers. But, you may want to check and make sure this mag will fit your rifle before you buy.
Even with that minor hiccup, this magazine is still one of the best blends of durability and price on the market. It’s an excellent magazine for any context.

2. Hexmag AR-15 Series 2 30 Round Magazine
Key Specs:
- Caliber:
223 Remington
- Capacity:

AR 15 Platform
Pros:
- Durable polymer construction.

- Some quality control issues.

This magazine features polymer construction. So, it’s more resistant to warping than metal magazines. And, it’s lighter than most metal magazines.
There’s a lead in ramp above the catch pocket for smoother magazine insertion, and stripper clip guide for easier refilling.
Inside the magazine, there’s an anti-tilt follower for smoother feeding.
The polymer is very thin, to save weight. This makes the magazine body less rigid than the beefier polymer magazines. However, it doesn’t seem to cause any reliability issues.
The only trouble with this magazine is the quality control. Most people get SENTRY Hexmags that function perfectly. But, some buyers have received magazines that had reliability issues. So, make sure you function check this magazine before you use it for anything serious.
However, even with this imperfection, the price still makes these magazines an incredibly attractive option for the budget-minded shooter and those who want a huge stockpile of magazines for training.
Stock magazines could pose some problems in the future that's why this is the most commonly AR-15 upgraded component on the rifles.

3. Brownells AR-15 Magazine 5.56mm
Key Specs:
- Cartridge:
5.56 mm NATO
- Capacity:
30 Rounds
- Material:
Aluminum
Pros:
- Better durability and reliability than standard USGI magazines.
- Magpul anti-tilt follower for smoother feeding.
- Hardcoat anodized finish.
- Easily drops free during reloads.
Cons:
- Heavier than a polymer magazine.
- Metal construction is prone to warping over time.
If you’re the type who wants a metal USGI magazine, the Brownells AR-15 Magazine 5.56mm is for you.
Brownells improved on the original USGI design by using a welded aluminum body for better durability and reliability. The follower is upgraded with a Magpul anti-tilt follower for smoother feeding than standard USGI magazines.
The exterior is covered with a hardcoat anodized finish to add corrosion resistance. The finish also reduces friction so your magazines reliably drop free during speed reloads.
All these factors add up to produce a metal magazine that performs just as well as most polymer magazines. Unfortunately, it’s still metal. So, it’s heavier than a polymer magazine. But, not by much.
And, even though it’s tougher than the standard USGI magazines, metal construction is more prone to warping than polymer magazines. This magazine will last for a very long time. But, check your feed lips periodically.
But, if you’re the type who prefers to run metal magazines, or if you just want a low cost alternative to high-end polymer magazines, this is probably the magazine for you.

4. Lancer Systems AR-15 30 Round L5AWM Magazine
Key Specs:
- Caliber:
223 Remington/5.56MM NATO
- Capacity:
30 Rounds
- Material:
Polymer
Pros:
- Excellent blend of price and quality.
- Hardened steel feed lips for smoother feeding.
- Polymer body and base plate for better impact resistance.
- Metal-on-metal magazine catch engagement.
- Translucent models available for visible round count.
Cons:
- Can be hard to seat completely on a closed bolt.
The Lancer Systems AR-15 30 Round L5AWM Magazine is a hybrid magazine in terms of both construction materials and price. It gives you the best qualities of metal and polymer, and it lands somewhere between USGI mags and high-end polymer magazines on the price spectrum.
First, the majority of this magazine is polymer. However, there’s a hardened steel sleeve at the top which promotes smoother feeding. And, the hardened steel feed lips are less prone to warping, because they’re supported by polymer.
The metal sleeve also engages the magazine catch for a solid, metal-on-metal hold when the magazine is seated in the magazine well.
So, this magazine is lighter and more impact resistant than a traditional metal magazine. But, it’s got metal where it matters.
These magazines also come in a variety of colors:
The translucent colors offer the benefit of being able to see how many rounds you have left in the magazine. And, it’s easier to see the rounds in a translucent magazine than it is in a traditional windowed magazine.
Some shooters have found that these Lancer Systems magazines can be difficult to seat completely when loading with a closed bolt. So, you should check the function before you run these magazines in your competition, tactical, or defensive rifle. But, open-bolt reloads are no problem, and the magazines seat fine with a good slap, even with the bolt closed.

5. Pro Mag AR-15 Roller Follower Steel Lined Magazine
Key Specs:
- Caliber:
223 Remington/5.56x45mm NATO
- Capacity:
30 Rounds
- Material:
Steel Lined Polymer
- Finish:
Black
Pros:
- Steel-lined polymer provides the benefits of polymer and steel magazines.
- Steel feed lips for smoother feeding.
- Metal-on-metal magazine catch engagement.
- Anti-tilt follower is equipped with a roller to improve reliability.
- Stippled exterior for better grip.
Cons:
- Requires more cleaning than most magazines.
- Not the best for shooting in super dirty conditions.
Pro Mag took a page out of the Glock handbook, and produced the Pro Mag AR-15 Roller Follower Steel Lined Magazine. It combines steel and polymer to produce the most reliable and durable AR-15 magazines on the market.
This magazine is essentially a polymer magazine wrapped around a steel sleeve. This produces an extremely tough and rigid body, with steel feed lips for smoother feeding. However, since the steel is supported by the polymer, it’s much more resistant to warping.
Pro Mag also utilized the steel lining on the magazine catch for a positive catch and minimal wobble when you seat the magazine.
The “roller follower” is a polymer anti-tilt follower with a roller on the front edge which reduces feeding friction. This improves reliability.
However, it adds a moving part to the magazine that needs to be kept clean to function properly. So, these magazines require more maintenance than most.
The outside of the body is stippled more than most polymer magazines. This provides a solid grip for ripping magazines out of tight pouches or malfunction clearance.
This Pro Mag magazine might not be the best for shooting in super dirty conditions. But, the performance and reliability in cleaner environments makes this magazine an excellent option for competition and tactical shooters.
The Final Shot
If you haven’t started stockpiling magazines, you definitely should. It’s not even about prepping for the apocalypse. It’s just easier to train, compete, and shoot for fun if you don’t have to fill up your magazine every five minutes.
Carrying an spare mag does give you more edge rather than filling everytime it runs out.
